How does Tempdrop work?

The Tempdrop wearable sensor is worn under your upper arm during sleep. It is kept in place with a comfortable elastic armband. Each night, it collects thousands of data points on your body temperature, your environmental factors, and, sleep motion.

After removing the sensor each morning, initiate a sync to the Tempdrop app ( Apple Store, Google Play) to retrieve your sleeping temperature result and sleep data* using Bluetooth Low-Energy (BLE) to your smartphone. The Tempdrop wearable sensor will replace the traditional method of BBT temping so you can stop losing sleep and take the stress out capturing a daily BBT result. 

The app also provides a fertility charting feature to track all your other fertility symptoms along with BBT that is automatically added to your chart. The sensor and app together provide an all-in-one ovulation tracking solution.
